ORGANS OF GOLD FISH CARASSIUS AURATUS AND THEIR EFFECT AMMONIAON BLOOD

The study was conducted on gold fish carassius auratus to show : 1.effect of different concentraion of coppr (2and 3 mg/L) and lead (25and 35 mg/L) on accumulation of these metals in different organs (liver,gut,kidney and muscles) exposed for 96 hours.Lead has a great ability to accumulate in tissue more than copper.The highest concentration of both metals was noted in liver and it was followed by gut, kidney and muscles. 2.effect of the above metals concentration on the levels of blood ammonia,for two time intervals (48 and 96 hours ) were studies also. There were proportional relationship between metals concentration the levels of ammonia in the blood . Ammonia concentration were affected by the presence of copper more than lead.
